How does wireless charging work? What is the farthest distance?

Generally about 0.9-2 meters high-power wireless charging transmission distance up to 5 meters wireless charging technology can be divided into low-power wireless charging and high-power wireless charging two ways. Low-power wireless charging often uses electricityMagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.

The principle of wireless charging: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.

If the charging efficiency is relatively normal and harmless to the human body, the farthest distance that can be done now should be 5-10cm, domestic micro goose technology, Qualcomm should be able to do it. And this is not the public familiar with Qi wireless charging, is magnetic resonance wireless charging, based on the principle of magnetic resonance. Although there are also 1 meter or even farther wireless charging technology, but the current charging power of these are too small, charging speed is too slow, difficult to put into daily use.

Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will be producedWhen a magnetic field is generated, other unenergized coils (the electrocuted coils on the mobile phone) close to the magnetic field will generate current to charge the mobile phone.

The core magnetic resonance medium and long distance wireless charging developed by Spurotin can successfully achieve wireless charging within one meter.

Wireless charging of new energy vehicles, coming soon

Most mobile phones today support wireless charging. You just need to put the phone on the wireless charging pad and charge it. Although the speed of wireless charging is slower than that of wired, there is noWire charging is simpler and faster to some extent. Wouldn't it be interesting to use this technology in our new energy vehicles? Recently, the National Standards Management Committee issued four national standards on wireless charging of electric vehicles.

Qualcomm vice president recently revealed that Qualcomm is developing an innovative wireless charging technology for cars, which is expected to be launched in the next 24 months. This indicates that in the future, we will witness a large number of new energy vehicles using Qualcomm technology on the road. However, on the question of price, Qualcomm will leave it to the automaker to give a clear answer.

Then to say that the wireless charging used by passenger cars before, the power is not as good as the efficiency of slow charging pile, and the current level can exceed the efficiency of slow charging. From this point, wireless charging has been qualified to be loaded into the car. However, the application of wireless charging technology to the field of new energy vehicles seems to be a very worthwhile thing, but the specific research and development process has encountered a number of problems.

What are the best wireless headphones? 2022 is the best year to buyThe ten Bluetooth headsets are all here.

1, SONY SONY is a well-known consumer electronics brand from Japan, and its product quality and durability are guaranteed. SONY launched the WF-1000XM4 headset with 20 ambient sound controllable noise cancellation function, intelligent noise cancellation, battery life of up to 32 hours. It uses Type-C charging mode, charging speed is fast. Overall, SONY's headphones are of the best quality and most durable. Rambler Among Bluetooth headset brands, Rambler is the best quality and most durable.

2, Bluetooth headset This is one of the most commonly used digital products,In the past few years, the price of Bluetooth headphones is generally high, until the rapid development of digital technology in the last two years, there has been a large number of affordable, easy-to-use Bluetooth headset products, and it is also very durable.

3, Bluetooth headset fans assemble! Today, I would like to recommend several ultra-long endurance Bluetooth headphones to you, so that you can enjoy the music at the same time, don't worry about the problem of insufficient power. Sony WF-1000XM4 I have personally tried SONY's WF-1000XM4 and it is super easy to use! It uses the latest Bluetooth technology, not only the connection is stable, while the sound quality is clear.

4, many people have a great misunderstanding of the word parity, that the parity of headphones often can only listen to a sound, in fact, a big mistake! Affordable headphones often pay attention to the needs of consumers, and can directly poke the needs of consumers. Next, I will recommend a few cost-effective Bluetooth headsets, which are very suitable for student party use.

5, South Carolina small pod Bluetooth headset - Price: 239 yuan - Bluetooth version: V3 - Recommended reasons: the use of a new generation of V3 Bluetooth chip, 13mm moving ring with an exclusive acoustic system to achieve 45ms low latency. This kindp>

Mi 10 and Mi 10pro What is the difference between domestic mobile phone which brand is good and worth starting

Difference 2: Different screen The peak brightness of the Mi 10 screen is only 1120nit, while the peak brightness of the Mi 10Pro screen reached 1200nit. In addition, the Xiaomi 10Pro uses a primary color screen 0, which has professional grade color accuracy. This means that the screen color performance of the Xiaomi 10Pro is more accurate and the color reproduction is stronger. distinctionBattery life and charging speed The Mi 10 battery capacity is 4780mAh, while the Mi 10Pro battery capacity is only 4500mAh.

Mi 10 is a 0cc*2 speaker; The Mi 10pro is a 2cc*2 speaker. The latter's speakers are better than the former, but the average person won't feel the difference. The Mi 10 does not support HDR10 display, but the Mi 10 Pro only eats. However, the resolution, size, and refresh rate of the authentication screen are actually the same. Color contrast Mi 10 comes in three colors, titanium silver black, ice sea blue, peach gold.
